A loose bottom stitch is almost always caused by insufficient top tension, which allows the bobbin thread to pull too much thread to the underside. The most common fixes are rethreading the top machine with the presser foot up, cleaning lint from the bobbin area, changing the needle, and increasing the upper thread tension dial.This video explains how to fix loose stitches on your sewing machine:
TO FIX LOOSED STITCHES ON YOUR SEWING;
1) Top Thread Not Seated Properly (Most Likely): The top thread may have missed the tension disks or the take-up lever.
2). Action: Re-thread the entire machine, ensuring the presser foot is up (which opens the tension disks to accept the thread).
3). Too Low Top Tension: The top thread tension is too low, so it doesn't pull the bobbin thread up.
4). Increase the upper thread tension dial to a higher number (e.g., from 3 to 4 or 5).
5). Bobbin Area Lint: Lint or bits of thread in the bobbin case interfere with tension.
6). Remove the bobbin, remove the needle plate, and thoroughly clean the bobbin case with a brush or vacuum.
7). Incorrect Bobbin Insertion/Winding: The bobbin might be in backward or not feeding through the tension spring.
😎. Remove the bobbin, re-wind it if it's uneven, and ensure it spins in the correct direction (usually counter-clockwise).Incorrect Needle: A dull, bent, or wrong-sized needle can cause stitching issues.
9).Replace the needle with a new one appropriate for your sewing machine
